发明名称 LENS SYSTEM FOR COLOR PHOTOGRAPHY
摘要 The color lens system includes a main objective lens and an annular series of independent color lenses positioned forwardly of the main objective lens; the inner diameter of the annular series of independent color lenses being equal to or slightly greater than the diameter of the main objective lens. Prismatic lenses are provided for each color lens, which lenses collect light rays from the object being photographed and direct the light rays to the color lenses, the rays from the color lenses being directed to the main objective lens. The color rays pass through the main objective lens and the focal length of the main objective controls the focal point of the color rays. The color system uses all colors of the spectrum and results in an improved color balance with resultant flatness of field to the edge of the aperture.
